The ZTrak™ M and R Series Mowers are equipped with either a side-discharge or Mulch On Demand™ 7-Iron PRO deck.

7-Iron PRO mower decks have demonstrated quality, performance, and durability. They deliver a high quality cut in diverse conditions.

Key features of the 7-Iron PRO mower deck:

Deck is stamped from 7-gauge, 0.179-in. (4.6-mm) steel to minimize the number of welds and provide a smooth underside with fewer sharp corners for reduced material buildup.

Significantly fewer welds on the deck shell to wear or break - it is stamped from a single sheet of steel rather than multiple fabrications. An anti-skid step on the deck provides easy machine mounting.

A deep-deck design of 5.5 in. (14 cm) delivers excellent airflow so material can be processed quickly and efficiently.

The wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.

Mower rectangular leading-edge reinforcement

Dual-captured anti-scalp wheel

Key features of the 7-Iron PRO mower deck:

Deck has rectangular leading deck edge reinforcement and the rounded corners of the stamped deck help distribute impact stress to reduce the potential of damage when the mower contacts trees, rocks, curbs, and other fixed obstacles.

Three 1-in. (2.5-cm), cold-forged spindles are heat-treated for strength without bulk and are supported by ball bearings, providing reliability and performance; spindle housings are ribbed cast aluminum providing both excellent strength and heat dissipation.

The front edge is raised above the blade plane to allow even cutting of tall grass and is reinforced with a square bar for durability. The front baffle has been redesigned to better manage airflow and control clippings.

The Mulch On Demand mower deck delivers unprecedented levels of productivity and versatility to commercial mower operation. With the ability to switch between side discharge and mulching operation with the flip of a lever as the operator mows, keeping most clippings out of landscaping features and where they are wanted is extremely easy.

Deck can be converted from a wide-open side discharge mode to a fully chambered mulching mode with a single move of a lever.

NOTE: Mulch On Demand decks are a balance between a side discharge deck and a side discharge deck with a mulching kit.

Deck is stamped from 7-gauge, 0.179-in. (4.6-mm) steel to minimize the number of welds and provide a smooth underside, with fewer sharp corners, for reduced material buildup.

Significantly fewer welds on the deck shell to wear or break- it is stamped from a single sheet of steel rather than multiple fabrications. Anti-skid step on the deck provides for easy machine mounting.

Mulch On Demand decks are superior to aftermarket chute blockers due to the movable baffles.

Wider and higher discharge opening provides even clipping dispersal for an excellent finished appearance in all conditions.

Three 1-in. (2.5 cm) cold-forged spindles are heat-treated for strength without bulk and are supported by ball bearings, providing reliability and performance; spindle housings are ribbed cast aluminum providing both excellent strength and heat dissipation.

The operator can select the ground speed and direction control simply by moving levers forward or reverse.

Positive neutral lock position for levers provides added safety.

Brake & Go operator-presence system returns levers to the neutral position when the brake pedal is actively engaged.

Starting the machines is as easy as starting a car. It no longer matters if the control levers are extended out or pulled in, as long as the parking brake is engaged. Just turn the key and go.

Wide-bend, large-diameter steering levers swing out easily for entry and exit from the operator platform.

Foot pegs

Foot pegs available as standard on R-spec Z900’s

Foot pegs help in providing the operator with a comfortable foot placement:

Location and angle of foot pegs can be adjusted for individual operator comfort.

Brake & Go starting system

Parking brake pedal (Z900R Series)

Parking brake lever (Z900 E and M Series)

The Brake & Go starting system is a John Deere exclusive. This feature makes the starting process on all ZTrak™ mowers easier, while also making it possible to remove two interlock switches from the machine.

The Brake & Go starting procedure helps a novice operator look and feel like a professional. To start the machine, the parking brake must be engaged. It does not matter whether the power take-off (PTO) switch is on or off, nor does it matter if the control levers are pulled in or in the out position.

As long as the parking brake is engaged, the machine will start. When the parking brake is applied, the control levers cannot be moved to the forward or reverse positions.

Adjustable levers

Adjustable levers

The motion control levers have two height positions and can also be adjusted forward or rearward within the slotted holes. The levers should be adjusted so the operator can achieve a full range of control operation comfortably.

Tracking adjustment

Tracking adjustment

The easy-to-turn (from-the-seat) tracking adjustment allows operators to keep their mowers straight and able to produce professional striping results.

Easy-to-operate height-of-cut adjustment enables on-the-go changes

Mower deck height adjustment knob

An easy-to-use cutting-height lift system allows the operator to adjust the mower deck height with no tools and minimal effort. The easy-to-grip knob allows operators to dial in the desired height of cut (HOC).

Cutting height can be adjusted from approximately 1 in. to 5.5 in. (2.5 cm to 14 cm). Each increment on the knob adjusts the HOC approximately 0.25 in. (0.64 cm). The deck can also be raised and locked in a transport position to provide maximum ground clearance when moving the machine from one area to another.

The transport lock function allows the deck to be returned to the previous HOC after being in the transport position:

Use the foot-lift pedal to lift the deck and engage the transport lock.

E and M Series 3-year, 1500-hour bumper-to-bumper warranty

An exclusive 2-year, unlimited hour/3-year, 1500-hour (whichever comes first) bumper-to-bumper warranty is standard for all John Deere E and M Series Mowers. The warranty is best in its class and places John Deere at the forefront of commercial mowing. It is also hassle free, with one company handling all of the paperwork.

NOTE: 36 months or 1500 hours, whichever comes first. For the first 24 months, there is no hour limitation.

R Series 3-year, 1500-hour bumper-to-bumper warranty

An exclusive 2-year, unlimited hour/3-year, 1500-hour (whichever comes first) bumper-to-bumper warranty is standard on all John Deere R Series mowers. The warranty is best in the industry and puts John Deere at the forefront of commercial mowing. It is also hassle free, with one company handling all of the paperwork.

NOTE: 36 months or 1500 hours, whichever comes first. For the first 24 months, there is no hour limitation.

The hydrostatic drive included with the R Series Mowers features two 13-cc (0.8-cu in.) unitized hydraulic pumps combined with commercial-grade, heavy-duty, 13-cc (0.8-cu in.) wheel motors into a single unit. The R Series drive units feature cross porting, where the hydraulic fluid from the side doing the least work is filtered and then fed into the input of the side doing the most work. This ensures that the coolest fluid is going into the side working the hardest in order to provide the best performance during extended hillside operation in the same direction.

One pump and one motor drive each wheel on the ZTrak™ R Series Mowers. This provides several benefits:

24x12N12 is also available as base code equipment for ZTrak Gas Mowers with 54 in., 60 in., and 72 in. (137-cm, 152-cm, and 183-cm) Mower Decks (ordering information available at Configurator on the Tweel model page)

The design of the Z900 Series makes many service components reachable and easily accessible from the ground.

Large, open engine compartment at the rear of the machine provides convenient servicing and ensures the engine heat is directed away from the operator.

Flip-up foot panel

Flip-up seat

Onboard maintenance chart

Maintenance chart

All ZTrak™ Mowers come with an onboard maintenance chart that is conveniently located inside the right-hand console. The service interval chart gives necessary service intervals.

Diagnostics

Hour meter (M Series pictured)

Diagnostic chart

The hour meter shows the number of hours the machine is run when the key switch is in the on position. It only counts the hours the engine is actually running. Machine diagnostics are the first step of a monitoring system to help operators quickly diagnose common downtime issues. A trouble code light is included on the hour meter.

Use of the hour meter and service interval chart helps determine when the machine will need service.

Rollover protective structure (ROPS) enhances operator safety

ROPS up

ROPS mid position

ROPS down position

The ZTrak™ Z900E, M, and R Series Mowers are equipped with a standard two-post folding ROPS and seat belt. The folding ROPS enhances operator safety and provides ample clearance when storing the mower in garages or sheds:

ISO21299 certification

Foldable

The ROPS system can be repositioned without the use of tools. Under normal operation, the ROPS should be in the up position. If operating in low clearance areas, they can be folded and secured out of the way. The ROPS can also be pinned halfway down to accommodate machines equipped with a material collection system.

On every John Deere ZTrak™ mower deck, there are three 1-in. (2.5-cm) spindles that are cold-forged and heat-treated for strength without bulk. The spindles are supported by precision ball bearings, providing great performance and reliability.

The spindle housing is made of aircraft-grade, ribbed cast aluminum on 48-in., 54-in., and 60-in. (122-cm, 137-cm, and 152-cm) decks, including Mulch On Demand™ configurations. This unique casting design embosses reinforcing gussets in the housing, which adds both strength and cooling surface area that stands up to commercial applications.

These spindles can be greased from the top and require no disassembly to reach. Grease channels provide lubrication to both bearings.

John Deere provides application-specific Environmental Protection Agency (EPA) approved field-installed propane conversion kits for specific John Deere Commercial Walk-Behind Mowers, QuikTrak Mowers, and ZTrak Mowers. The conversion kits include all components required to convert the engines to operate on propane fuel. Single-tank or dual-tank brackets (depending on the vehicle) are provided for securely holding the propane tank(s) to the vehicle.

Propane tanks are not included.

An optional altitude kit is required when operating at altitudes above 2000 ft (610 m). The operator’s manual with the propane conversion kit provides further details. Parts must be ordered separately through John Deere Parts.

Propane facts:

Propane is flammable and commonly used as a fuel.

The molecular formula of propane is C3H8, and it is in the family of liquefied petroleum gases (LP gases). The other LP gases include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof.

Propane is commonly available and has proven to be a dependable, safe, economical, and clean-burning fuel. It can be used as household fuel, industrial fuel, and fuel for internal combustion engines. Propane has been used as a fuel since 1910.

At atmospheric pressure, propane boils at -44°F (-42.2°C), meaning it typically exists as a vapor. However, when contained under pressure, such as in a propane cylinder, it can exist as a liquid.

Propane is naturally odorless, but includes an additive odorant, usually mercaptan, which gives it a distinct odor.

Vapor propane is heavier than air, meaning it will settle in low areas such as along the ground or in drains.

Accessories and Attachments

Lighting

This light kit signals to others that the machine is approaching. The light is positioned on top of the canopy or on a rollover protective structure (ROPS). It has a breakaway bracket, so that if struck the light can move out of the way.

Miscellaneous

This light kit signals that unit is approaching. The light is positioned on top of the canopy or on rollover protective structure (ROPS) with a breakaway bracket; this ensures that, if struck, the light will not break but will move out of the way.

The jack for the mid-mount mower allows easy access to the underside of the mower for maintenance or blade changing while in the field. The kit contains everything necessary to install the jack onto the front of a mower.

Mulch Kits

The mulching attachment allows converting the mowers so they can be used to perform the mulching function (grass or leaves) of this system.

The attachment consists of special mulching blades, mulch baffles to direct the clippings into the blade for recutting, and a discharge closure and hardware. The adjustable baffle can be moved to one of five positions to match conditions using the convenient wing nuts.

Operating tips when mulching:

Mow when the grass is dry.

Observe the one-third rule.

No more than one-third of the grass blade should be cut off at one time. This allows more efficient mulching and will promote the continued good health of the grass. If the desired cut height cannot be achieved by cutting off one-third, or there is clumping of the clippings, it may be required to cut higher; wait a day, then lower the mower and make a second pass.

5/5

Purchased this mower last summer with the 54" MOD deck and the Twheels. This machine is very robust and will absolutely fly and cut at the same time. My only complaint is the blade RPM's are so fast that when in a dusty area it will cover you. I'm thinking this is just zero turns in general though. I love the 7 Iron deck and how it is one solid stamped piece of steel. This is a better design than the welded decks you see on other competitors mowers. The welds can serve as a weak point if the weld penetration is not consistent. That is ultimately what lead me into purchasing this mower over another brands. It was bar far not the most affordable but quality is not free. Overall I would buy this again in a heartbeat.
